<p>Is it possible to do a crater run that compares the parent of  <a href="https://github.com/rust-lang/rust/issues/64470" target="_blank" title="https://github.com/rust-lang/rust/issues/64470">#64470</a> with a combination of <a href="https://github.com/rust-lang/rust/issues/64470" target="_blank" title="https://github.com/rust-lang/rust/issues/64470">#64470</a> and <a href="https://github.com/rust-lang/rust/issues/65389" target="_blank" title="https://github.com/rust-lang/rust/issues/65389">#65389</a>? (I'd need to create a try build that contains the latter two). I think the bug that was fixed by <a href="https://github.com/rust-lang/rust/issues/65389" target="_blank" title="https://github.com/rust-lang/rust/issues/65389">#65389</a> will come up quite often and maybe make it tough to find new bugs.</p>
